Mammalian cells are sensitive to the physical properties of their micro-environment such as the stiffness and geometry of the substrate. It is known that the stiffness of the substrate plays a key role in the process of mammalian myogenesis. However, the effect of geometrical constraints on the process of myogenic differentiation needs to be explored further. Here, we show that the geometrical ...

understanding the relationship between sink and source in maize is of prime importance in maize growing regions. in this study, a field experiment was carried out during spring and summer 2007 in the experimental field of the college of agriculture, shiraz university, to examine the effects of source restriction (defoliation) on sink size (yield and its components) of  sc704 maize hybrid.  a fa...

The experiment was carried out at Regional Agricultural Research Station, Bangladesh Agricultural Research Institute (BARI), Jessore to evaluate the performance of different varieties of hybrid maize under intercropping systems with groundnut in rabi seasons to find out the suitable intercropping system in increasing crop productivity and profitability of consecutive two years (2004 and 2005). ...

Nitrogen is one of the most important factor affecting maize (Zea mays L.) yield and income of smallholders under semiarid climates. Field experiments were conducted to investigate the impact of different N-fertilizer sources [urea, calcium ammonium nitrate (CAN), and ammonium sulfate (AS)] and rates (50, 100, 150, and 200 kg ha-1) on umber of rows ear-1 (NOR ear-1), number of seeds row-1 (NOS ...

The study analyzed factors that influence farmer’s participation in hybrid maize seed production in the study area. A Logit analysis was used to analyze factors influencing farmer’s participation in hybrid maize seed production while T-test was used to analyze if there is difference in the mean yields of farmers growing hybrid seeds and those involved in local maize production. Structured quest...

Given that the majority of maize farmers in Kenya are small-scale, improvement in maize production must focus on increased production per unit area. While hybrid maize varieties outperform local open pollinated varieties under conventional farming practices, their relative performance has not been tested under small-scale intensive production practices. A study was conducted in 2013 in Kitale, ...
